Step 1
Locate the car's water pump. The water pump is on the front of the engine. It will be behind the car's fan blade, if your car has a fan.
-
Step 2
Crank the engine when you want to inspect the car water pump for leaks. It's important to allow the engine to heat up. This allows the thermostat to open on your engine so that your water pump can circulate the fluids.
-
Step 3
Look for water pump leaks after your engine has been running for several minutes. The water pump has a shaft that is attached to the fan on the outside. The shaft goes through the water pump housing. This has a seal and bearing. The seal is what keeps the water from leaking out of the shaft. Inside the shaft of the water pump, there is an impeller which circulates water through the engine.
-
Step 4
Inspect the gasket around the water pump that mounts to the engine housing. The gasket is another part that could be leaking. Make sure all bolts are tight. Make sure the gasket is not blown out. If there are no leaks, the gasket (along with all parts mentioned in Step 3) should be dry.
-
Step 5
Check all hoses near your car's water pump for leaks. Many times, hoses leaking will look as if your water pump is leaking. If you discover a leaky hose, it will save you a lot of time and money. Hoses are cheaper to replace than water pumps.

on 3/22/2008 today i went to check my water in my 1989 Nissan, Pulsar and i noticed there was green fluid in the water. what could that be? could it be coolant? and what does that mean if it is leaking into my water compartment? should i not drive it until I can get my mechanic to check it? thanks heaps.
